DRIVING DOWN THE HIGHWAY A YEAR AND A HALF AGO WHEN I HIT AN UNEVEN PATCH OF PAVEMENT. MY TRUCK VIBRATED LIKE IT WAS GOING TO FALL APART. I THOUGHT I'D BLOWN OUT A TIRED. I GOT OUT AND EVERYTHING WAS FINE. I DROVE AROUND FOR ANOTHER COUPLE OF DAYS (BELOW 50 MPH) UNTIL I HAD THE NEED TO GET ON THE FREEWAY. GOT UP TO SPEED 75 AND HIT AN UNEVEN SURFACE, CAUSING MY TRUCK TO VIBRATE AGAIN VERY FRIGHTENING.... TOOK THE TRUCK INTO THE DEALERSHIP WHERE THEY INSTALLED DUAL STEERING STABILIZERS. EVERYTHING WORKED OK UNTIL LAST WEEK. I NOTICED THAT NOW MY TRUCK CATCHES WHEN I TURN RIGHT, AND IS DIFFICULT TO STEER. I NOTICED LEFT STABILIZER IS WORN OUT, I REPLACED IT TONIGHT. THIS DID NOT FIX THE ISSUE. I'M TAKING IT BACK TO THE DEALER AND I WOULD GUESS THERE IS GOING TO BE A MAJOR FRONT END ISSUE. I HOPE THE DEATH WOBBLE DIDN'T SCREW UP MY TRUCK. *TR

TRAVELING @55 MPH, WHEN I RAN OVER A SMALL POT HOLE. MY TRUCK SHOOK VIOLENTLY AND WAS EXTREMELY DIFFICULT TO CONTROL AND STAY IN THE LANE OF TRAFFIC AND SLOW DOWN TO A SPEED WHEREIN I COULD BRING MY VEHICLE UNDER CONTROL ( 35 MPH). VISUAL INSPECTION SHOWED NO ANOMALIES. MY TIRES DID NOT APPEAR TO BE DAMAGED AS IF I HAD RUN OVER AN OBJECT. THERE WERE NO OBJECTS IN THE HIGHWAY. APPROXIMATELY 60 MINUTES LATER, AFTER I FINISHED MY ERRAND AND WAS RETURNING HOME, ANOTHER INCIDENT OCCURRED. THIS AS MORE VIOLENT ERRATIC FRONT END JUMPING AND I HAD TO MOVE TO TWO LANES TO STOP MY VEHICLE. AGAIN, INSPECTION SHOWED NOTHING OUT OF THE ORDINARY. I THEN PROCEEDED DIRECTLY TO MY FORD DEALERSHIP WHERE I SPOKE WITH A SERVICE PERSON. I REQUESTED THAT MY VEHICLE BE PLACED ON A LIFT TO GET A COMPLETE INSPECTION. THE MANAGER REFUSED TO DO THIS STATING THAT THIS WAS A CONTINENTAL TIRE PROBLEM BECAUSE OF "STIFF SIDEWALLS"AND THAT I SHOULD RETURN IN A FEW DAYS FOR AN INSPECTION AT THAT TIME AND THEY WOULD PLACE A "STEERING DAMPER" ON MY TRUCK ( OF WHICH I MIGHT BE FINANCIALLY RESPONSIBLE" AND THAT MAY OR MAY NOT CORRECT THE PROBLEM. I FEEL THIS IS AN EXTREMELY DANGEROUS SITUATION, ONE IN WHICH I AM VERY FORTUNATE NOT BE HURT, MY VEHICLE DAMAGED, OR SOMEONE ELSE INJURED. MY DEALERSHIP IS POOH-POOHING IT AS IF IT IS NOTHING. *TR
